Introduction

This exercise is to familiarize the user with the collect view app provided in the Contiki OS source code. It basically involves a sink mote and one or more than one source motes. The source motes send their sensor, network, power and node properties to the sink. A java app presents all this compiled data in a graphical manner.

You Will Learn

  • How to upload an introductory code for UDP source and sink.
  • How to program nodes and collect data through the collect-view GUI.
  • Things to see on the collect-view GUI.

Relevant Directories

  • /contiki/examples/collect/ - This has the shell code for collect view and the various targets.
  • /contiki/examples/ipv6/rpl-collect/ - This has the codes which are to be uploaded to the source and sink motes for UDP communication.
  • /contiki/tools/collect-view/ - This contains the java file for the collect view GUI.
  • /contiki/apps/collect-view/ - This contains the codes corresponding to the targets mentioned in the examples folder.

Connect the Tmote Sky

Before continuing with the tutorial, plug 2 Tmote Sky into the computer's USB port, one for the source and the other for the sink.

In order to transfer the ownership of the contiki directories use the following command. 

 sudo chown :user /dev/ttyUSB0

 sudo chown :user /dev/ttyUSB1

Using the Source Code

Step 1

Go to /examples/collect/ directory.

Step 2

Now we need to program one mote as the sink and the other as source. We will use a predefined target called sky to upload the code in the motes.

For sink: 

 make TARGET=sky MOTES=/dev/ttyUSB0 collect-view-shell.upload

For source: 

 make TARGET=sky MOTES=/dev/ttyUSB1 collect-view-shell.upload

Step 3

Now we would like to see the transfer and depiction of data on the collect-view GUI. For that to happen, go to /tools/collect-view directory and run "ant" to build the collect viewer. 

 ant run

Note - In order to edit GUI java files go to the /src directory.

Step 4

To view the data collected at the sink, go to the generated /tools/collect-view/dist and run - 

 java -jar collect-view.jar /dev/ttyUSB0

Step 5

In the collect window from the Tools menu, select "Run Init script" and in the "Node Control" tab and click on "Start Collect." This will enable the communication between the source and the sender and you will be able to see the received statistics in a graphical manner.

Using the GUI

Step 1

Once the motes are connected to the USB ports, go to /tools/collect-view directory and run "ant" to build the collect viewer. 

 ant run

Step 2

Press the "Program Nodes..." button as seen on the GUI.

Step 3

Disconnect all except one node from the USB ports. Press the "Connect to serial" button. The disconnected motes should be connected to independent power sources.

Step 3

Now in order to collect various statistics, press "Send Collect" button.

Step 4

Set the various "Collect Settings" based on how frequently the data is to be collected and then press "Send command to nodes" button.

Step 5

Now go through the other tabs on the GUI to study and analyze the statistics plotted.

Using Cooja Simulator

Step 1

Go to /tools/cooja/ directory and run "ant" to start the simulator. 

 ant run

When Cooja is up and running, it will start with a blue window.

Step 2

To create a new simulation, click on the File menu, choose 'New Simulation', name the simulation and click on 'Create'.

Step 3

To add Motes to the simulation, click on the Motes-> Add motes-> Create a new mote type-> and select the type of mote to be added in the network.

In the 'Create Mote Type' window, choose a suitable name for the mote type. In the 'Contiki process/ Firmware' option, follow the path examples/collect and select the 'collect-view-shell.c' program. Compile and click Create.

In the 'Add mote' window that pops up, enter the number of motes and alter the position intervals as required and click 'Add motes'. The number of motes added to the network is now shown in the 'Network' window.

Step 4

To start the simulation, Click on 'Start' in the 'Simulation Control' window.

Right click on any mote in the 'Network' window, click on 'Mote tools for created mote type' and select 'collect view'. The 'Collect View' application starts.

Set the various 'Collect Settings' based on how frequently the data is to be collected, click on 'Send command to nodes' button and then 'Start Collect'. This will enable the communication between the source and the sender and you will be able to see the received statistics in a graphical manner.

Things to See on the GUI

Topological graphs

  • Sensor Map
  • Network Graph

Sensor Related Plots

These are subject to the availability of a particular type of sensor on the motes.

  • Temperature Sensor - Average Temperatue and Temperature.
  • Humidity Sensor - Relative Humidity.
  • Battery Sensor - Battery Indicator and Battery Voltage.
  • Light Sensor - Light 1 and Light 2.

Network Metrics Related Plots

  • Neighbours
  • Beacon Interval
  • Network Hops
    • Over Time
    • Per Node
  • Router Metric (Over Time)
    • Instantaneous
    • Average
  • ETX (Over Time)
  • Next Hop (Over Time)
  • Latency
  • Lost Packets (Over Time)
  • Received Packets
    • Over Time
    • Per Node
    • Every 5 min

Power Related Plots

  • Average Power
  • Instantaneous Power
  • Power History
  • Radio Duty Cycle

Other Tabs

  • Node Info - This gives a summary of all the nodes and their statistics.
  • Serial Console - The user can interact directly with the mote, sending commands to read and transmit data.
